[jira] [Closed] (SPARK-7460) Provide DataFrame.zip (analog of RDD.zip) to merge two data frames

     [ https://issues.apache.org/jira/browse/SPARK-7460?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Reynold Xin closed SPARK-7460.
------------------------------
    Resolution: Won't Fix

Closing this one since [~rams] doesn't think it is that important anymore, and I haven't heard a lot of demand yet.

I'm not sure if it is super useful to have this API, and it is also pretty hard to get right in a distributed setting (i.e. the two dataframes can have inconsistent number of rows). We can revisit this if there is stronger demand.

> an analog of RDD1.zip(RDD2) for data frames allows us to merge two data frames without stepping down to the RDD layer and back. (syntactic sugar)
